It is a further object of the present invention to provide a sighting device which maybe readily assembled and dis-assembled, and yet need only be adjusted one time to the requirements of the individual user.

A further object of the present invention is to provide a device of the character described which will be inexpensive to manufacture, and yet will be reliable to a high degree in use.

The foregoing and other objects of the invention are accomplished by providing a blow gun pipe having a discharge end and a month end. On the discharge end of the blow tube a sight support arm is placed so as to be perpendicular to the longitudinal axis of the pipe. A series of calibrations may be extended around the blow pipe periphery. A reference indicator may be mounted on the arm so that the bar may be aligned according to the desired angle as evidenced by the reference indicator pointing to one of the various calibration lines. The calibrations and reference indicator are optional features of the invention. Slidably mounted on the stem is a sighting element.

The sighting element may be adjusted on the bar ac cording to the distance betweenthe users mouth and eye. The arm may be rotated with respect to the longitudinal axis of the blow pipe depending upon which eye the user wishes to use for sighting purposes, and the eye piece may be positioned radially of the pipe to compensate for the distance from the users mouth to his eye. The additional calibrations on the blow pipe are for the purposes of accurately repositioning the sighting means for additional use. V

In a preferred embodiment the blow pipe is provided with a longitudinal key slot to receive a mating key mounted within a mouthpiece. The mouthpiece has flattened end portion which is placed within the mouth.

The central calibration of the series of calibrations on the blow pipe is located in a plane perpendicular to the reference plane of the mouthpiece, and since the mouthpiece is keyed to the blow pipe, the same reference plane is established for the blow pipe. Also, the reference indicator on the arm allows it to be aligned with the mouthpiece reference plane.

The invention and its advantages may best be understood from the following description of a preferred specific embodiment, read in connection with the accompanying drawings, in which:

FIG. 1 is a perspective view of a preferred embodiment of the invention;

FIG. 2 is an end elevational'view showing the arm FIG. 7 is an end elevational view of the embodiment of FIG. 6; and

FIG. 8 is a partial cross-sectional view taken along lines 8-8 of FIG. 7. I v

In FIG. 3, a blow pipe generally indicated by reference numeral 10 is cylindrical in shape and has an outer wall 11 and a smooth inner wall 12. Located at one end 13 of said pipe 10 is a key slot 14 having an end wall 15 and parallel walls 16 which flare out as at 17 and join smoothly with end wall 13 of said pipe. Spaced from the other end 18 of said pipe are a series of calibrations 19 for the purposes hereinafter appearing.

Designed to fit on the end 13 of said tube 10 is a I mouthpiece 20 having a main body portion 21 with an inner diameter slightly greater than the diameter of outer wall 11 of the tube so as to form a snug fit thereon. Said mouthpiece also has a flattened portion 22 which may be comfortably gripped by the mouth or teeth.

Located within said mouthpiece is a key 23 designed tomate with said key slots 14. As can best be seen in FIG. 4, telescoping of said mouthpiece over the end of said tube with said key in said key slot, provides a single reference plane for both the mouthpiece and the tube.

The reference plane is determined by the placement of the mouthpiece within the users mouth.

As further seen in FIG. 3, the sighting apparatus generally consists of a support arm 24 having an upwardly extending portion 25 and asymmetrically circularly expanded lower portion 26 ending in downwardly extending resilient fingers 27. The inner diameter 26a of said circular portion 26 is slightly less than that of the outer diameter of wall 11 of tube 10. Located on said circular portion 26 along the longitudinal axis of said bar 24 is a reference indicator 28 for the purpose hereinafter appearmg.

Further comprising the sighting device is a sighting In operation, the blow tube with the sighting device is assembled by first placing the mouthpiece on the blow pipe with the' key 23 placed in key slot 14 thus providing a desired reference plane for both the mouthpiece and the tube. It should be noted that although this is one method of providing the single reference plane, other means may be used such as placing reference line indicators on the vof the pipe as shown is FIG. 1.

mouthpiece and the tube and adjusting the two elements until the indicator lines are coincident with each other.'

The sighting element is then placed on the upper portion of the arm 24, the fingers 27 of the arm are spread slightly and the arm is placed on the blow pipe, the circular portion frictionally and rotatably engaging the end 18 As cannow be seen in FIG. 1 the calibrations 19 are positioned so that'the centrally located calibration determines a plane perpendicular to the reference plane of the mouthpiece and the blow tube, and when the reference indicator is coincident with this calibration line, then the arm 24 is also located in a plane perpendicular to the reference plane and blow pipe. V

To adjust the sighting device for an individual user,

' the mouthpiece is placed in position within the mouth and the arm 24 is rotated either clockwise shown in FIG. 2 or counterclockwise, depending upon which eye the user desires to use until the plane of the arm intersects the sight line of the desired eye. The sighting element is then adjusted upwardly or downwardly so as to locate the sighting ring within the line of sight of the user. Accordingly, the sighting device has now been adjusted to compensate for the distance between the m uth and eye of the user in a vertical plane and the br' nose and the eye of the user in a horizontal 1e.

It will be appreciated that the present invention provides an inexpensive and easily adjustable sighting device which allows the user a great deal of accuracy.

A modification of the present invention is shown in FIG. 6 and comprises a blow tube 100 having an outer wall 111, an inner wall 112, and calibrations 19" spaced from one end of said tube. It is further 'provi a bar 240 having a rectilinear portion 250, a cular portion 260 and downwardly extending fire The blow pipe further includes a reference indi' located along the central axis of the bar. 240 is further provided with a sliding eyepiece 290 having a sighting ring 300, a slot central wall 310 and 'netrical parallel ears 320 and 330.

The reference plane is determined by reference wire 35 which passes diametrical. I cylindrical stipport tube 36 and is adhesively held in place thereto. Said support tube has an outer annular shoulder 37 from which extends the cylindrical portion 38 having an outer diameter slightly less than that of the inner diameter of the sighting ring.

In operation the sighting eyepiece is placed upon the bar, and the bar is placed upon the blow tube as previously described. The support tube 36 is then'joined to the sighting eyepiece by placingthe cylindrical portion 38 within the sighting ring 300 where it maintains a slidable, friction fit. The reference wire 35 may then be aligned with a horizontal hair line on a target, and'the same accurate positioning may be obtained after adjust ment for the previously mentioned horizontal and vertical distances comprising the distance from the users mouth and eye.

Once a user has adjusted the sighting device to his I tor 28d own particular needs, by simply noting the calibration on i the tube coincident with the reference indicator or by putting an appropriate scratch mark, for example, and doing the same with the eyepiece, the user may disassemble the blow gun and sighting device and later reassemble the same without going to the necessity of re adjusting the sighting apparatus before each use. f

It will be obvious that the sighting device described may be used on other types of toy guns and the like other than blow tubes. Also it is evident from the foregoing description that those skilled in the art will be able to (0) a sighting element adjustable longitudinally of said 7 arm;
